Study Notes
Electric Motors and Generators
- Electric motors convert electrical energy into mechanical energy.
- Possible power sources for electric motors include batteries, direct current (DC), and alternating current (AC) power supplies.
- Electric motors can be classified based on their power source, construction, and application, such as DC motors, AC motors, stepper motors, and servo motors.
- Electric generators, on the other hand, convert mechanical energy into electrical energy, differing from electric motors in their energy conversion direction.
- Standardized motors are designed to ensure interchangeability, making it easier to replace or upgrade motors in various applications.
